* It is incorrect to use var_align() in linker code: it depends on current_settings.alignment, which is valid only while compiling, not while linking. Replaced with size_2_align().

+ Internal linker: process unreferenced .pdata sections on x86_64-win64, restores the possibility to use GAS on win64 (which got broken by introducing SEH).

+ Internal linker: base support for sections that aren't referenced but must be linked if section referenced by them is linked (like win64 .pdata). Actual handling is still to be implemented in descendant classes.

* COFF linker: postpone import section generation until unreferenced sections (and imports) are removed, and put all remaining imports into a single section. This is much more efficient than generating multiple smart-linkable import sections and immediately discarding a good half of them.

- TObjData.sectiontype2options: removed oso_keep flags. They don't have any effect here because this function is used only during assembling, and oso_keep cannot be represented in object files and therefore gets lost before linking.

* Don't calculate data position of each object section. Instead, write out a copy of exesection's memory image, i.e. every objsection is placed at the same offset from its owning exesection both on disk and in memory. This approach is simpler and works regardless of alignment requirements, while existing one could work only if SectionDataAlign<=SectionMemAlign.

* Internal linker: fixed alignment routines. Neither of existing ones is suitable for 64-bit targets: cutils.align() is 32-bit only and moreover signed, system.align() crashes on zero alignment values and handles only pointer size of source platform.

+ ELF linker. Works on x86_64-linux and i386-linux good enough to pass the testsuite, but still requires a lot of work in nearly all aspects. In particular, no attempt to resolve symbols from shared libs is done, everything is just treated as imports. Symbol versioning isn't supported either.

+ Extend TObjRelocation to hold untranslated platform-specific relocation types. This allows to avoid translating relocations into generic format when reading object files (which is just waste of time), and allows TObjRelocationType enumeration contain only types that are actually produced by compiler.
